What Is The Difference Between A 12 And 14 Rough In Toilet? How To Know If Your Toilet Is 10 Inches Or 12 Inches Conclusion One of the most crucial elements of installing a new toilet is the toilet rough-in. This is the distance from the wall of your bathroom to the center of your toilet’s floor drain.
You’re going to run into serious installation issues if you place your toilet either too close to or too far from the wall.
An overview of how to manage the rough-in measurements is provided below.
HOW DO I KNOW WHAT MY TOILET’S ROUGH-IN SIZE IS?
The majority of toilets are constructed with a 12 inch rough-in size. Having said that, some models or bathrooms may have 10 inches.
On rare cases, you might even find a rough-in of 14 inches.
Make careful to take the measurements in advance at all times. You want to buy a toilet that works with your bathroom when you go shopping for one.
If you wish to determine the rough-in size, you must measure the following elements:
The distance from the back wall at which the flange will be installed The clearance from left to right There was enough room in the bowl’s front for comfort. where the cold water line is located You won’t be able to correctly set the flange if you place the toilet too close to the wall. Additionally, you should ensure that the model can be connected to all other plumbing components without difficulty.
HOW FAR OFF THE WALL SHOULD THE TOILET BE
How far the toilet should be from the wall should be the main consideration when determining rough-in size. Generally speaking, you want to position the middle of your flange 12 inches away from the wall.
You can still fit a toilet in a 12 inch space even if it has a rough-in size of 10 inches.
One thing to keep in mind is that you shouldn’t measure the toilet’s placement from the base of the wall’s molding. Measure the distance from the finished wall itself.
This could significantly alter the outcome depending on how thick your molding is.
On the other hand, the thickness of the wall should be taken into consideration if you’re employing stud walls rather than finished ones. If you’re measuring from an unfinished wall, you should aim for 12.5 inches rather than the normal 12 because drywall often measures 0.5 inches.
Any toilet model’s rough-in size is listed on the specification sheet. Most models come in a 12-inch size, but some also come in 10- and 14-inch sizes.
HOW MUCH CLEARANCE FOR FIXTURES OR WALLS FROM THE TOILET CENTER? You must have a particular amount of space from the center of the toilet before you can reach the bathtub, sink, another wall, or any other fixture. This provides space for you to properly install the model and its plumbing.
The distance between the flange and any barrier to the left or right must be at least 15 inches.
You must also factor in wall thickness while examining a stud wall. Therefore, you need to leave 15.5 inches between the toilet flange and an exposed, unpainted wall.
If you’re considering adding tile to the wall, be sure to consider the thickness as well.
HOW FAR IS IT TO THE WALL FROM THE TOILET’S FRONT? There needs to be a particular amount of room in front of the toilet. After all, you want to be able to sit down comfortably!
Depending on the local codes, there will be different rules for this. The minimum standard for local codes that follow the International Plumbing Code is 21 inches.
That spacing rises to 24 inches for local rules that follow the Uniform Plumbing Code.
The municipal codes of your city or town should be known to plumbers working in your area. If you’re having problems locating information about the specifics, you can speak with one.
The distance is measured between the toilet and any obstacles, such as a door, a wall, or other furniture. Having said that, you don’t need this much area in front of a door to the bathroom that is open.
It only applies when the door is shut.
WHERE DOES THE COLD WATER SUPPLY LINE GO? Your toilet must be connected to the cold water supply line. After each flush, it will receive the refilled tank from there.
Thankfully, measuring for this line is not too difficult. First, find the flange’s center. Following that, measure six inches to the left.
Once you’ve located it, take a vertical measurement of seven inches above the floor tiles. That is high enough to prevent damaging the majority of base molding types while remaining low enough to stay out of the way.
You will need to notch the trim if your measurement is too low.
Plumbers frequently install the supply line six inches above the ground. Technically speaking, there is nothing wrong with that, however you might need to change any trim that is higher than 5 inches.
WHAT DIFFERS A 12 FROM A 14 ROUGH IN A TOILET? The size of the rough in is the primary distinction between these toilets. Because this is a more typical size, a 12 inch model is more prevalent than a 14 inch one.
When consumers need to have less room taken up behind their toilet tank, a 14 inch rough-in is occasionally employed.
HOW TO DETERMINE WHETHER YOUR TOILET IS 10 OR 12 INCHES
Whether the rough-in is 10 or 12 inches should be specified on the specs page when buying a new toilet.
Simply take a measurement from the center of the flange to the back wall to see what model you currently have. Which is larger, 10 or 12 inches?
Make sure you don’t take the wall’s base molding into account.
A 12 inch rough-in can accommodate a 10 inch toilet. But there will be some extra room behind it.
You should only consider 10 inch rough-in alternatives if your flange is only 10 inches from the wall.
CONCLUSION Your plumbing system and the type of toilet you have will determine the rough-in size. Although 12 inches is the most common size, 10 and 14 inch variants are occasionally available.
A 12-inch flange arrangement may accommodate a rough-in model of 10 and 12 inches. The distance between the center of the flange and the back wall is measured.
Talk to a professional plumber about the requirements if you’re confused how to find the local building rules for your toilet installation.
